筏基结构迷宫式水蓄冷的模拟分析

Simulation analysis of labyrinth chilled water storage system applying raft foundations as water tanks

提出利用建筑物筏板型基础作为水蓄冷槽体,实现迷宫式水蓄冷。以上海某项目为例,对其两块筏基区域采取不同的蓄冷水流线设计,分别建立了CFD模型,模拟了水蓄冷系统的蓄冷及释冷效果。结合模拟结果,计算了系统的蓄冷效率,分析了蓄冷/释冷水流线布置对系统蓄冷效率及削峰能力的影响。

Presents an idea about applying the raft foundations as the water tanks to achieve the labyrinth chilled water storage.Taking an actual protect in Shanghai as an example and adopting different water flow line designs for two areas separately,sets up the CFD modes,and simulates the cool storage and discharge effects of the chilled water storage system.With the simulation results,calculates the storage efficiency,and analyses the influence of water flow line on the storage efficiency and peak load shifting.
